From 0ec572f05721f430cf8470595da8c3d5e25567de Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 12 Feb 2019 09:56:57 -0300 Subject: [PATCH] tools feature: Undef _GNU_SOURCE at the end of feature tests Since we get all the tests in a single .c file for a first test, tools/build/feature/test-all.c, if individual tests set that define and fail to undef it at its end, then it the test-all.c build will fail due to defining _GNU_SOURCE multiple times, getting us to the slow path, so undef it at the end in tests that define it.
